Can someone describe what these functions do?

[jcl43]

def swime(lst):
    p = lst[0]
    S = []
    B = []
    for x in lst:
        if x < p:
            S.append(x)
        else:
            B.append(x)
    return S + swerve(B)    
 
def swerve(lst):
    result = []
    for x in lst:
        if x > 0:
            result.append(x)
    result.sort()
    return result
 
 

With these two functions, I'm not really sure what the first one does ? Can anyone explain it to me ? I understand the swerve function but not the swime one 0.o

it's the same as swerve() only it uses the first element of lst as treshold instead of 0.

It appears that swime() may be the primary function. It breaks up a list into two lists (S and B), S with items that evaluate less than list element 0 and B with list element 0 and the others that evaluate greater than list element 0. It then returns the sum of S and the list returned by swerve(B).
